The superficial inguinal ring (subcutaneous inguinal ring or external inguinal ring) is an anatomical structure in the anterior wall of the mammalian abdomen. It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve, the genital branch of the genitofemoral nerve, and the spermatic cord (in men) or the round ligament (in women). At the other end of the canal, the deep inguinal ring forms the entrance.[1]
It is found within the aponeurosis of the external oblique, immediately above the crest of the pubis, 1 centimeter above and Superolateral to the pubic tubercle. It has medial and lateral crura. [2]
Clinical significance
The superficial ring is palpable[3] under normal conditions. It becomes dilated in a condition called athletic pubalgia. Abdominal contents may protrude through the ring in inguinal hernia.
